Description

The TPA31xxD2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100 W / 2 Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without external heat sink on a single layer PCB.

Key Features

  • 1 Supports Multiple Output Configurations - 2 × 50 W Into a 4-Ω BTL Load at 21 V (TPA3116D2) - 2 × 30 W Into a 8-Ω BTL Load at 24 V (TPA3118D2) - 2 × 15 W Into a 8-Ω BTL Load at 15 V (TPA3130D2)
  • Wide Voltage Range: 4.5 V to 26 V
  • Efficient Class-D Operation - >90% Power Efficiency Combined With Low Idle Loss Greatly Reduces Heat Sink Size - Advanced Modulation Schemes
  • Multiple Switching Frequencies - AM Avoidance - Master and Slave Synchronization - Up to 1.2-MHz Switching Frequency
  • Feedback Power-Stage Architecture With High PSRR Reduces PSU Requirements
  • Programmable Power Limit
  • Differential and Single-Ended Inputs
  • Stereo and Mono Mode With Single-Filter Mono Configuration
  • Single Power Supply Reduces Component Count
  • Integrated Self-Protection Circuits Including Overvoltage, Undervoltage, Overtemperature, DCDetect, and Short Circuit With Error Reporting
